Receivers

For anyone starting an AR build from the ground up, you can't go wrong with choosing high-quality components. Our stripped receivers are the very same ones used in our rifle builds, manufactured, machined and finished to our exacting standards. Both the forged JP-15 and billet CTR-02 models accept all standard Mil-spec components but rise above most any others on the market. Even our Mil-spec JP-15 receivers must face high reject rate attrition before we'll put our name on them.

We also offer the great value of our Lower with Trigger (LWT) receivers, which includes a complete JP fire control package installed by our shop techs for a great value play.

All stripped lower receivers or sets can also be personalized with a custom lasermark from our library or with art of your own.

Side-Charge Complete Receiver Kits

For those home builders looking to bring some side-charge action into their next project, our complete gunsmith kits are the answer. In addition to the high-quality billet receivers, these kits include the proprietary JP side-charging handle as well as a complete JP bolt carrier group with cutouts to accommodate the side-charging system—everything you need to get your build off the ground.

Our PSC-11 kits offer a choice of carrier style and will fit any Mil-spec lower receiver while our large-frame PSC-12 kits come in two versions to accommodate either DPMS- or Armalite-pattern lowers. The LRP-07 matched receiver sets are available in two versions with our standard, streamlined competition upper or our military version with dust cover and forward assist.

"one size fits all" trigger module

In the past, JP has designed and marketed a high quality single-stage module as part of our ongoing pursuit of improvements to the AR-15 platform. We knew we had the best single-stage trigger available but needed a fool proof way to enable the customer to install it. So, we ended up following the trend with our own drop-in modular trigger.

Experience is a valuable teacher, and we’ve been in this game longer than most. In the end, we came to the realization that there are simply some significant limitations to the modular trigger concept.

Unlike other firearms that were designed from the ground up to incorporate modular fire control packs, the AR-15 and AR-10 platforms were never designed to work with such modules. The possible runout in trigger/hammer pin hole locations and safety selector position on receivers made by countless manufacturers can cause potential compatibility and even safety concerns.

The module always represented a compromise in many respects. It needed to be manufactured to adequately fit and function in a wide variety of lowers compromising with the peculiarities of each, but “adequate” and “compromising” are not words we use here at JP. We and our customers have always set the elevation of our sights a number of clicks higher, and we feel that most modules are not suitable for anything other than recreational or non-critical competition applications where proper function is a luxury rather than a necessity. Moreover, modules simply do not have an extended track record for reliability, and many have been recalled for reliability or safety issues.

We very seldom talk about “cost” here at JP; we talk about value. We are generally not the most or least expensive, but we are almost always the best value for your dollar. With the modules inherent compromises and the $300 price tag, we had to come up with a value-based solution.

So here it is: we are offering one of our JP-15 lower receivers as the module with the complete installation of either our Competition or Tactical Fire Control System. JP will factory install a JP fire control kit into a genuine JP-15 forged lower receiver for almost the same price as the competition’s modular trigger alone.

MicroFit Takedown Pins

Sloppy receiver fit is annoying and cheapens the feel of your rifle. It also hamstrings your rifle's accuracy potential. Then, there're receivers that are too tight thanks to finish buildup like Cerakote.

JP MicroFit Takedown Pins are the answer to poor receiver fit. Available in standard, oversized and undersized, MicroFit pins provide a receiver fit that satisfies by compensating for the loose or tight fit that can't be helped.

A good receiver fit should be snug but not frustratingly tight. That was the goal with our original JP Tension Pin, but MicroFit pins provide the same result without tool-assisted takedown. For all but the very sloppiest receivers, MicroFit is your ticket to a more refined rifle.

Now standard on all JP rifles, MicroFit pins receive the same polished black QPQ coating as our bolt carriers for high durability, corrosion resistance and of course, sheet prettiness.

FAQ

Gas-operated rifle actions operate essentially the same for a light shooting .204 Ruger as it does for a heavy .458 SOCOM. The barrel pressures and recoil are different, but the internal moving parts are remarkably similar. They both compress the recoil spring by the same amount, so you should have no problems with any of our receivers in those calibers.
